G., Viersen, Germany ApplicationMarch 1'7, 1938, Serial No. 196,488 In Germany March 20, 1937 6 Claims.

This invention relates to machines for forming sweetmeats such astablets or drops in which a string or rope of plastic sugar is fed intoan endless train of travelling molds whereby it is 5 severed intopieces, and in' which embossing elements are associated with the moldsand are moved axially to emboss or form the pieces into drops ortablets.

With machines of this nature it is usual for the m sweets to bedischarged from the train of molds (where the latter open) still hangingtogether by their fins in chain formation. For various reasons known inthe art it is preferred that the drops should be discharged from themolding machine separately.

Machines are known adapted more particularly To this end the embossingelements are arranged so that the embossing positions of the embossersin adjacent molds are staggered, whereby adjacent pieces of plasticsugar will be severed by the embossing elements at the-position wherethey assume the staggered relation. The staggering of the embossingelements may be efiected by providing alternate elements with short andlong shafts. Alternatively the embossing heads of adjacent elements maybe long and short.

In the accompanying drawings which illustrate diagrammatically a sweetmolding and embossing machine according to the invention:

Figure 1 is a cross-sectional elevation taken on the line l-| of Figure2,

Figure 2 is a longitudinal section taken on the line 2-2 of Figure 1,

Figure 3 is a developed plan corresponding to the machine shown inFigures 1 and 2 showing a suficient number of adjacent molds to coverthe complete operation of feeding the rope of plastic sugar to the moldsand the'discharge of the emhaving an inner mold part 5 formed with aseries of half molds 6. This inner mold part is mounted between discs Iand 8 which are carried upon the shaft 9 mounted in bearings [0 in theframe H of the machine. The disc I is provided with an axial sleeveportion l2' and flanges 13 and M, the flange l4 being provided with orformed as a gear l5 which meshes with a pinion (notshown) by which themolds are rotated. The disc 8 is also provided with a sleeve l6 andflange portions I1 and i8.

Pivotally carried by the flange I3 is a series of outer mold elements 19which are adapted to co-operate with the inner mold part 5 to formcomplete mold apertures. The movable mold elements l9 also providecutting devices by which. the rope of plastic sugar indicated by thereference 39 is severed into suitable pieces as the mold elements H! aremoved to their closed position. The closing of the mold elements I9 iseffected by 20 their engagement with "a stationary cam surface 20 duringthe rotation of the mold parts.

When the pivoted outer mold elements I9 are fully closed they areretained in this position by a portion 20a, of the cam 20, such portionbeing 5 concentric with the axis of revolution. The cam 20, 20a issecured to the frame or casing by means of bolts 2!.

Co-operating with the molds is a series of plunger or embossing elements22, two of these elements being provided for each mold aperture.

The embossers are mounted upon rods 23 which are guided in apertures inthe flanges l3, l4 and I1, I8 respectively. On the outer end of theserods heads 24 are provided which are adapted to engage stationary cams25, 26 arranged at either side of the machine and secured to the frameby bolts 21. These cams are adapted to cause the embossing plungers tomove inwardly in the mold apertures whereby the sweets are shaped andembossed in the desired manner.

In order that adjacent sweets shall be separated from one another theembossing elements when in their final embossing position are adapted tobe staggered, as will be seen in Figure 3, so that the embossing headsact to sever the fins between adjacent sweets. For the purpose ofstaggering the embossers the rods 23' of adjacent embossing elements arealternately short and long, it being appreciated that in one pair of alents the rod on one side of the machine will a long rod while thecorresponding rod of the pair will be a short one, as will be clearlyobserved from the developed plan.

In order to move the embossers outwardly after 5 32 in the framing I lof the machine. The tablets the embossing operation, each embosser rod23 is provided with a projection 28 which is adapted to engage astationary cam 29 as the train of molds rotates, there being a cam ateach side of the machine. These projections extend outwardly while attheir inner ends they are guided by rods 30 carried in the flanges l3,l4 and I1, I8.

After the embossing has been completed the pivoted outer mold parts l9are adapted to be opened as indicated in the right hand half of Figure1, such opening being by gravity or positively by the engagement of theparts IS with a stationary cam, whereby the tablets or drops are allowedto fall from the molds on to a guide plate or chute 3| extending throughan aperture will fall freely of one another owing to the absence of finsdue to the staggered embossing action.

The rope of plastic sugar 39 is guided into the molds through anaperture 33 in the framing of the machine and is'suitably supported by aguide 34.

According to a modified form (see Figure 4) the staggering of theembossing positions of the embossing plungers is effected by providingembossing heads 35, 36 of difierent depth. Thus in one pair ofco-operating embossers the head is deeper than the head 36, while in theadjacent pair the position is reversed, the head 31 being shallow whilethe head 38 is deeper. In this form the rods 23 of the embossers are allof the same length,

I claim:

1. A machine for molding sweets in tablet or drop form from a rope ofplastic sugar confectionery, comprising an endless train of moldsadapted to sever pieces from said rope, means for moving said moldsthrough a circuit, pairs -of co-operating embossing elements in each ofsaid molds, means for moving the embossing ele ments towards one anotherto mold and emboss the pieces, and means for moving adjacent pairs ofembossing elementsinto embossing positions which are staggeredrelatively to one another and for retaining said elements in saidstaggered positions until the molds are opened to release the tabletswhereby adjacent tablets or drops are severed from one another and aredischarged singly from the machine.

2. A machine as claimed in claim 1 wherein the embossing elements aremounted upon rods, stationary cams for moving the embossing elementsaxially, the rods of adjacent embossing elements being alternately longand short to provide said staggering.

3. A machine as claimed in claim 1 wherein the embossing elementscomprise embossing heads mounted upon rods, stationary cams for movingthe embossing elements axially, the embossing heads of adjacent elementsbeing alternately deep and shallow to provide said staggering.

4. A machine for molding sweets in tablet or drop form from a rope of'plasticsugar confectionery, comprising a rotary mold device having aninner mold part comprising a contiguous series of mold recesses, aseries of co-operating dividing mold elements disp'laceably mounted withrespect to the inner mold part, cam means for closing the dividing moldelements on to the inner mold part to form a series of mold apertures,pairs of co-operating embossing elements located in said mold apertures,cams for moving the embossing elements parallel to the axis ofrevolution of the rotary mold to and from the embossing positions, themovements of the embossing elements being such that the embossingpositions-of adjacent pairs of elements are relatively staggered andthat the embossing elements remain in staggered position until they areopened to release the tablets.

5. A machine as claimed in claim 4 wherein the embossing elements arecarried by alternately long and short rods whereby said staggering isattained.

6. A machine as claimed in claim 4 wherein adjacent embossing elementsare formed with alternately deep and shallow heads, whereby saidstaggering is attained.
